This invention is for a coin-freed or operated vending machine and has for an object to provide a machine which will pack and deliver vendible goods upon the insertion of a coin. Another ob- .iect is to provide a vending machine for edible products or foodstuff that will cook or heat said goods prior to sale. A further object is to provide a machine having a plurality of vending positions but which, upon the insertion of a coin at any selected position will only deliver the goods to that position, while a still further object of the invention is to provide improved packing mechanism in a coin-freed or operatedvending machine. 15 These and other objects are achieved by the construction of the machine illustrated in the accompanying drawings, in which Figures 1A and 1B show, in sectional elevation, contiguous portions of the machine. 20 Figure 2i's a plan of that portion of the machine shown in Figure 1A.

Referring to Figures 1-2, the machine comprises a hopper l2 into which chips, either cooked or uncooked, are thrown. These chips fall to the bottom l3 of this hopper and from there may be picked up by spaced plates on the conveyor 5 it that deliver them into a container adapted to be heated, such as the tank l5 containing 011 or fat. The form of conveyor here illustrated is of a convenient and conventional type, but the invention herein claimed is not limited to this 10 showing in the drawings. The oil tank may be provided with a perforated false bottom I6 on which the chips rest. If the chips are supplied to the hopper l2 in the raw state then they are cooked in this tank l5 (which is supplied with 15 suitable heating apparatus, not shown). If they are supplied to the hopper i2 already cooked or partially cooked, then they are warmed up or the cooking is finished in the tank i5. Above the cooking and/or heating tank l5 there is a conveyor I! having spaced conveyor plates 18 and this conveyor, which travels in a clockwise direction, picks up the chips and carries them up the inclined and perforated wall I9, the oil meanwhile draining back through the perforations into the base of the tank. The mechanism for driving the conveyors l4 and I1 is not shown, since its specific nature is not a. part of the present invention and may be varied within wide limits. Suflice it to say that these conveyors may be geared with some driven part of the apparatus, such as the shaft I53 or 40, in a manner to give the desired motions to them. As the chips reach the lip of this wall l9 they fall over into a hopper 20 whence they pass into a; tub 21 that is positioned below it. This tub 2i rests upon a platform 22 and has at its front end a hook-shaped finger 23. The platform 22 is carried upon parallel pivoted links 24, 25 as in a balance or scale and the link 25 is provided with a balance weight 26, so that when the requisite quantity by weight of chips has accumulated in the tub 2|, the latter sinks until the finger 23 is brought into engagement with any one of a number of perforations 21 in a travelling conveyor band 28. This conveyor band thereupon carries the tub upwards to a receptacle 29 (Figure 1B), which may comprise a heated storage oven.

Each tub is provided with wheels or runners 30 and, when the tub is delivered to the receptacle 29 such wheels or runners are received within opposed channel-shaped tracks 32, of a runway. This run-way is downwardly inclined towards a hopper 33 at the front end of the receptacle 29, and the tub therefore runs down the in- '55 cline until the finger 23 comes against a pivoted catch 34. Figure 1B shows in dotted lines a tub held in the run-way by this catch.

The catch 34 is carried upon a pivoted lever 35 connected to a rod 36 and is tripped at periodic intervals by the following mechanism. The rod 36 is drawn downwards by a tension spring 3'! and carries at its lower end a roller 38 that cooperates with a cam 39 upon a cross shaft Ml in the base of the machine. There is a suitable recess 4| in this cam so that when the roller 38 drops into this recess, the catch 3% is moved out of the way of the finger 23 on the tub and permits this tub to run forward and downward over the curved nose of the run-way so that its contents are discharged through the hopper 33. The empty tub continues down the run-way until it is brought to rest (Figure LA) by a pivoted stop 42 adjacent to the platform 22. When the platform 22 sinks with the weight of a full tub it closes contacts M, M to complete a circuit through a solenoid 45 by means of which the stop (12 is drawn downwards against the weight (it to free the aforesaid empty tub and to permit it to run on to the platform as the previous tub is removed therefrom by the conveyor belt 27.

It will be appreciated that the tubs 20, after discharging their contents down the hopper 33 from the oven or chamber 29 are in an inverted position, and in order to return same to the normal position, a pair of arms ltd may be located beneath the downwardly inclined run-way formed by the tracks 32, with which arms a pin or lug HQ projecting from each of the tub sides engages as the inverted tub travels down the run-way. The sharp contact between the pins lit and arms its swings the tub over on its wheels or runners 3t, and when the tub is the right way up it is prevented from swinging further by a centre plate or rail llll preferably chamfered as shown and positioned between the tracks 32.

Other means may, however, be provided for returning the tubs to the normal position after tipping.

Turning now to the mechanism by which the cooked or reheated chips thus discharged into the hopper 33 are packed, in that portion of the machine that is shown in Figure 118 there is a platform ill upon which a stack of bags is placed, mouths uppermost. These bags, which are indicated at Ma, are pressed or fed forwards by a plate Q8 that is moved by a weight it. The foremost bag of the stack is positioned almost directly below a plate 5d forming one wall of a chute 58a leading from beneath the hopper and is arranged to be opened by bag-opening fingers 52, (ii. Slidably mounted on this wall 5d there is a slider 5i carrying two of the bag-opening fingers 52; this slider is reciprocated vertically through the medium of a lever 52a; pivoted at 53, connecting rod 56, and a tension spring 55, but is normally held in the raised position, together with the fingers 52, by spring 55. A pin 56 on one side of a rotating disc ilila on the cross shaft d0 coacts with the upper end of the lever 52a to rock or pivot said lever on the pivot 53 and draw down the slider 50 with fingers 52 against the spring 55 and when so operated a gravity catch Ell falls into engagement with a recess 52b to retain the lever 52a in the displaced position and the slider 51] lowered; it being understood that the fingers 52 when lowered enter the foremost of the bags Ma.

The other side of the chute 5212 that forms a continuation of the hopper 33 is constituted by a plate 59 on which a slider 60, carrying the other two bag-opening fingers BI, is slidably mounted. This plate 69 actually forms the vertical side or part of a member which is angle or L-shaped in side elevation, the horizontal or foot portion 82 of it being movable horizontally in guides on the machine frame or other fixed part to bring the fingers 6! close to the fingers 52. The horizontal movements of the plate are controlled by means of a pin 53 carried upon a disc 64 on a cross shaft 65. which pin engages with the forked end of a pivoted lever 66, the latter being coupled by a connecting rod 67! to the part 62. The vertical movements of the slider 6t and the fingers 6! carried thereby are controlled as followsz-On the cross shaft 65 there is a cam plate 68, (Figures 1B and 2), the face of which is cut with a groove in which a pin on the end of a lever (it engages. This lever is fixed to a transverse spindle it that at its opposed ends carries levers ill; the latter are connected by links l2 to a further transverse spindle E3 in the centre of the length of which there is a lever i l pivoted upon a rocking link it and connected to the slider til.

On the underside of the part 62 there is a spring arm it that, when the part 62 is pushed forwards, is moved against a projection H on the underside of the vertical plate 5b and is thereby defiected so that it enters the mouth of the foremost bag and partially opens it. In order to facilitate the opening,'the forward edge of the bag mouth is lower than the other. It will, of course, be appreciated that the part 82 is advanced towards the bag while the slider til is in its raised position (as is also the slider 54). The sliders 5i and 60 are then lowered so that the fingers 52 and iii are'inserted in the partially opened bag. Next, the part 62 is retracted so that the fingers iii are drawn away from the fingers 52, and the bag itii thereby completely opened.

The mechanism is so timed that the measured quantity of chips is not discharged down through the hopper 33 until the bag positioned below it has been opened to receive it.

At the appropriate moment a second pin 58 on the opposite side of the disc 60a engages an extension of the catch 57! and knocks same out of engagement with the recess 52b in lever 52a so as to permit the spring 55 to raise the slider 5i and fingers 52. The fingers 52 are thus raised clear of the bag, but before the other fingers ti are raised they are first moved horizontally to draw the filled bag into line with mechanism which now operates to close and seal the mouth of the bag. Such mechanism comprises dies it and 79 (Figures 5, and 14), the die is being carried upon an arm 80 that is formed on its undersurface with a ramp 8i and is pivoted to a block 82. The block 82 is connected to the upper end of a lever 83 pivoted at 86 and movable by means of a pin 85 on a disc 86 that is mounted on the cross-shaft 65. By these means the die is advanced towards the bag mouth. In its advance the ramp at on the arm 80 moves over a roller Bl so that the die '09 is raised over the bag mouth and is then permitted to drop down on the far, i. e. rear side of the bag.

Immediately thereafter, the die 18 is moved by a lever 88 and a pin 89 upon a disc 90 also on the cross-shaft 65, (Figure 4). The bag mouth is gripped between these dies and the two walls of said bag are pressed together. In plan, however, the co-operating faces of the two dies 18, 19 are not straight, the'die 18 being formed with projections 18a and the die 19 having a cooperating recess 190. so that the walls of the bag adjacent to the bag mouth are corrugated to correspond; see Figure 14. This permits a skewer to be stuck through the walls of the bag so that it transfixes them from one side to the other and then back again. The dies are each provided with a recess 9I extending the entire length to facilitate this skewering operation. The apparatus by which the skewers are forced through the bag mouth is shown in Figures 6, '7, and 8. Each skewer 92 consists of a length of wire which is bent and twisted to the shape shown in Figure 9, that is to say the skewer has at its forward end a loop and at its rear end a fork formed by the ends 93 of the wire, and such a skewer may be used as a fork in eating the chips. A supply of these skewers is carried in a magazine 94, where they lie horizontally one on topof the other. Beneath the magazine there is a horizontal reciprocatable bag-piercing needle 95. This needle is cut longitudinally with a recess as is shown in Figure '1 to accommodate a skewer, the forward end of said recess being chamfered as at 95a, and at the rear end of this recess there is a nose 96 that fits inside the fork 93 of the skewer. The needle is pushed forwards from the base of the magazine by means of levers worked from a cam 91a on a shaft I56 (Fig. 1B) and in its forward movement it carries the skewer with it. It passes through the slots 9I in the dies 18, 19 and transfixes the walls of the bag I66 adjacent to the mouth from side to side. The needle 95 is then retired, but upon its backward movement a light spring I61 fixed to the front die 19 coacts with the rear bifurcated end of the skewer 93 and prevents the return or withdrawal of said skewer so that the latter holds the bag mouth closed when. the bag is subsequently released by the dies.

The skewers 92 in the magazine 94 are supported upon a lip at the bottom of a spring plate 91. Attached to this plate there is a screw 98 that extends through the wall of the magazine and at its outer end is provided with a knurled nut 99. This screw 98, between the wall of the magazine and the nut 99, is engaged by the end of a bell crank lever I00. The other end of this bell crank lever is positioned in the path of a small vertical pin IOI on the needle 95 so that as the needle moves forward the bell crank lever I is rocked and the plate 91 drawn sideways to release the skewers in the magazine. These skewers therefore fall on to the top of the needle. As the needle is retracted, after the bag has been pierced, the lip on the plate 91 moves beneath the bottom skewer but one, while the bottom skeweritself falls into the recess in the needle for use in the next cycle of operations in the machine.

After the bag has been thus sealed the die 18 is then retired by means of pin I02 on the disc 90, which pin makes contact with a lever I03, and the die 19 is retired by a similar arrangement of pin I04 on disk 86 and lever I05. As it is retired the die 19 is lifted over the bag month by means of the ramp BI and roller 81.

The filled bag then falls from the plate 41 on which it has so far been supported through trap doors I06 into a vertical chute I01 (Figs. 13 and 3). The operation of these trap doors may be automatically controlled through mechanism operated from a suitable shaft, as 40; but as the specific nature of this control is not essential to the present invention it is not illustrated.

The vending machine shown in the drawings is provided with a number of coin slots H at different positions (of which two are indicated in Figure 1B) and it is, therefore, necessary to deliver a bag of chips to that position where the person-has inserted his coins and not to any other position. For this reason subsidiary chutes, numbered I06 to H2, lead off fromv the vertical chute I01, one to each vending position. At the mouth of each subsidiary chuiethere is ahinged trap door II3 arranged to cover the chute. In Figure 3, the trap door appropriate to the subsidiary chute I09 is shown opened so that a package falling down the main chute I01 will be deflected by the door II3 into the chute I09 where it thereupon strikes a flap II4 that is connected to the trap door H3 and thus closes the latter. The obtuse angle between the trap door H3 and its associated flap H4 is approximately the same as the obtuse angle between .the main chute I01 and the subsidiary chutes.

It is, of course, necessary to provide that no two trap doors shall be open at the same time and suitable apparatus. whereby this is ensured is shown on Figures 3, 15, and 16. Referring particularly to Figure "15, there is at each vending position a coin slot II5 leading to a vertical coin chute I I6 and an inclined branch coin chute II1, both of which communicate with a money receptacle II8. Just below the junction of the two chutes there is a pivoted lever II9 having at its lower end a hook I20 that projects across the chute H6. The machine is arranged to deliver a packet upon the receipt of two coins, and the first coin that is pushed through the slot II5 falls down and rests upon the end I20 of the lever H9. The second .coin strikes the top of this first coin and is deflected thereby down the branch chute II1, where it makes contact with an arm I2I pivoted at I22 and in so doing establishes electrical contact between this arm and the chute II1 to complete an electrical circuit through asolenoid I23.

Connected to the arm I2I there is a spring arm I24 that is maintained in engagement with a contact I25 from which a. lead extends to the solenoid I23. From the core of the solenoid a rod I26 extends to the end of a pivoted lever I21 that has at its other end a balance weight I28. When the solenoid I23 is energized the core is sucked down and the lever I21 is rocked against the weight I28. This movement is communicated by means of hook I29 and arm I30 to that arm I2I against which the coin rests, which arm I2I is thereby moved sufiiciently to permit the coin to slide past it down to the receptacle H8, and the circuit through the solenoid is thus broken. The weighted end of the lever I21 is connected by a connecting rod I3I to the lever H9 and this same movement therefore serves to rock the lever H9 and thus the first coin is permitted to fall down the chute II6 to the receptacle H8; The various parts are then returned to their original positions by the weight I28.

If for any reason it is desired to prevent the insertion of coins, meansare provided whereby the attendant may obstruct the slot II5. For example, there may be a pivoted ,arm I32 normally held in a position clear of the slot but which, when a chain I33 or the like is pulled by the attendant, is moved across the slot to obstruct it.

The closing of the circuit through the solenoid I23 also closes a circuit through a solenoid 834 operation 01 which serves to prepare the appropriate subsidiary chute to deliver the package to the corresponding vending position, and also serves indirectly to block all the other subsidiary chutes. As is shown in Figure 3, there is a solenoid I34 ior each coin inserting (or vending) position and for each oi! the subsidiary chutes I08 to H2. Adjacent to each solenoid 1184 there is a vertical spindle I35 connected by a link 53B and arm I31 tothe appropriate trap lid. This ver-- tical spindle carries a collar 038, arranged to cooperate with catches' H39 and Mt], and a pin Ml arranged to co-operate with a spring contact M2. When by the insertion of coins at any coin slot M5 the appropriate solenoids lit and tilt are energized, one of the catches 089 is moved by that solenoid H34 to an inoperative position so that the adjacent spindle H35 falls by gravity and thereby opens one of the traps M8 so that a packet of chips is delivered down that subsidiary delivery chute that is appropriate to the vending position at which the coins were inserted. As the spindle i135 falls the pin Mi on it makes contact with the spring contact 0412 and thereby closes the circuit through a common solenoid M9, the core of that solenoid being thereby moved towards the left. lit is this movement that locks all the other subsidiary delivery chutes, because the catches We are thereby placed under the collars H38 of the remaining trap-operating rods 035, so that these rods cannot fail to open their trapdoors even if one of the other solenoids i3 3 (appropriate to another vending position) is energized. In order to bias the catches Mi! to positions in which they will prevent the descent of the associated rods H35 there is a horizontal slidable shaft E66 attached to the plunger of the common solenoid [1G9 and carrying as many spaced pins MS as there are catches Mb, each of which pins engages with a leaf-spring M l projmting from the associated catch. Thus when the shaft 1168 is moved to the left upon energization of the solenoid M9 (following the insertion of a coin) the descent of one of all the springs i ll are deflected to set the catches Mil, which incidentally are weighted so that when the solenoid Mil is subsequently de-energized and the shaft Mill moved to the right they rock to their inoperative positions. The said solenoid M9 is or" course deenergized when the package, having passed into the appropriate delivery chute, depresses the nap lid to raise the associated rod I135 and thereby break contacts M0, M32.

In addition to opening the required subsidiary chute, the energizing of a solenoid i-Qi and the descent of the associated rod i255 also serves to start the bag-filling and sealing apparatus. It will also be observed that the top end of each rod or spindle i325 bears, when that spindle is in its raised position, against a spring contact [1 35 and holds the latter away from a stationary contact t lt. When any spindle 0335 is permitted to fall by the energization of its appropriate solenoid 613d, the contact M5 associated with that spindle moves against the co-operating contact M6 and thereby closes a circuit through a further solenoid id'i. This solenoid completes a circuit from the mains through an electro-magnetic clutch Md and thereby starts the before described bag filling and sealing apparatus to deliver a bag of chips.

In the modified construction of apparatus illustrated in Figure 16, the first coin which is inserted through the slot H5 i'alls down the vertical coin chute H8 and comes to rest on a pivoted hook "2. In falling the coin comes into engagement with the tail portion I13 01 a freely pivoted pawl H4 so as to swing said pawl on its pivot and 5 bring an inclined tip I15 into a position at the junction between the vertical delivery chute H6 and an inclined branch chute H1, as indicated in dotted lines in Figure 16. In this position the tip I15 of the pawl H4 deflects the next inserted l0 coin .down the branch chute ill where it falls on the extremity oi a comparatively long lever' H6 and depresses said lever until the coin falls clear of the chute ill. The lever H6 is pivoted at ill and attached to this pivot is an insulated l5 block in carrying a spring-bridge contact member M9 which on depression of the lever "6 by the coin makes contact with a pair of spaced contacts M0 and in so doing completes the circuit of the appropriate solenoid i341. The pivot il'i also 20 carries a catch Hill which on depression of the lever i776 coacts with a pivoted pawl 082. This serves to hold the contacts lit and ltd in engagement until delivery is given of the goods, after which through the medium of a rod in 25 (which is suitably coupled to the appropriate one of the rods (135 shown in Figure 3) pivoted bell crank lever [ltd and hooked link it?) coacting with pin 586, the said pawl are is pulled forward out of engagement with the catch Hill.

When the lever ilii has been depressed by a second inserted coin, the first inserted coin is released from the hook 272 by means of an arm or lever i871 and coupling rod or link its extending from said arm tell to the hook Hi2, and 35 when the hook W2 is swung out of the chute lid and the coin falls, the pivoted pawl lid is swung back by gravity to its normal position with the tail portion i713 projecting through said chute M6 and the tip i withdrawn from said chute. After delivery of the goods and the disengagement of the catch till on pivot ill from the pawl 182, a counter-weight idtl raises the lever illii to its normal position and disengages the contacts W9 and ltd.

Whichever of the two illustrated constructions is adopted, as stated previously, the bag of chips is deflected by the opened trap door M3 down the appropriate one of the subsidiary delivery chutes the to M2. In its passage into such subsidiary chute, it presses down a flap lit and thereby closes the trap door and also moves the associated spindle its upwards. The upward movement of this spindle breaks the contact at Mi and i 32 and the circuit through the common solenoid i 59 and thereby releases the spring pres sure upon the catches Mil. These catches thereupon move to their inoperative positions so that if by the insertion of coins at any other vending position a solenoid i3 5 is energized then the 60 trap door Mil appropriate to that solenoid and to that vending position may be opened.

When a spindle B35 reaches its upper position it is held by the associated catch ltd. On reaching such upper position it breaks the contacts M5 65 and M6 and the circuit through the solenoid Ml thereby freeing the electro-magnetic clutch M8 to bring the machine to a stand still.

The machine is driven from a continuously rotating electric motor H50. This motor drives, by 70 means of a worm HM and a worm wheel E52, 2. cross shaft H53 upon which the electro-magnetic clutch M8 is mounted. From this cross shaft a belt 654 extends backwardly to drive the continuously moving perforated conveyor 28. A fur- 75 ther belt I55 extends forwardly to drive the cross shaft, 40 and it is this belt I55 that is started and stopped by the electro-magnetic clutch I48. The two cross shafts 40 and 65 are connected by bevel gearing and by a longitudinal shaft I56.

From the foregoing description, it will be appreciated that the insertion of coins into a coin slot H5 at any of the vending positions places in train the mechanism shown in Figure 3, to prepare the delivery chutes to deliver a package only to that position and then starts the machine working (by the electro-magnetic clutch I48) to pack anddeliver a-measured quantity of chips.

The conveyors I4 and I1 may be intermittently driven through any suitable drive transmission from the cross shaft I53 or other convenient motion shaft of the machine, or they may be driven and controlled independently of the packing and delivery mechanism. In cases where the conveyors I4 and II are independently operated, the insertion of a coin or coins operates to withdraw the chips from the oven or heated chamber 29 wherein a stock may be maintained.

It may sometimes be desirable to construct the machine so that every so often it returns money or delivers a suitable check or token to the purchaser of the packet of chips. For this purpose adjacent to the receptacle 29 (Figure 1B) there is a magazine I51 for coins or tokens, having in its base an outlet slot I58 in line with an opening I59 in the wall of said receptacle 29 above the chute 33. Below this magazine there is a ratchet wheel I60 carrying a finger ISI. This ratchet wheel is stepped round by means of a pawl I62, bell crank lever I63 and a push rod I 64 that is oscillated from a cam I65 on the longitudinal shaft I56. Once in each revolution of the ratchet wheel I60, the finger I6I passes through the bottom of the magazine I51 and sweeps out one or two coins (the number of coins of course depending on the height of the finger) so that,

they fall down the chute 33 and are packed into a packet of chips.
